Providing power to the US is the government's responsibility in the same way that governments funding maintenance of public roads, paying for teachers, and paying for firefighters doesn't always generate money yet is subsidized or wholly paid for by a government entity. The fact that the government doesn't have to fully pay for the nuclear plant (because its offset by the money the plant makes) makes it less that the government has to spend. If anything, I'd like the government to completely take over nuclear plants so that there's less profits for private entities. Yes nuclear is more expensive than renewables, but an already existing nuclear plant is cheaper than a new one, which is way better than fossil fuels, the real enemy. Not to mention, in how long will renewable take to make up the almost 10% of energy that the plant supplies to California? Instantly? no. It takes time, and until that time, we need all the energy generation we can get, ESPECIALLY if its not a fossil fuel based one. Radioactive waste? Definitely a problem, in a couple hundred years. Right now, all the radioactive waste the US has ever made would fill up a football field, 10 yards deep. Not really a high priority problem especially compared to the risk that global warming risks.

All in all, it feels like we shouldn't let the search for a perfect solution, impede temporary good enough solutions.
